N-net Web Management Industrial Switch
Managed switches support the SNMP protocol.
N-net NT-INM1042GF-AF4 is Web Management Industrial Switch with 2 4 POE 100Base-TX ports up to 2 Gigabit Ethernet 1000Base-X SFP ports.
The SNMP protocol is composed of a set of simple network communication specifications.
It is a industrial managed and redundancy Ethernet POE Switch, supporting standerd IEEE802.3AF and IEEE802.3AT. This switch also supports POE-auto-check fuction.
It can complete all basic network management tasks, has little demand for network resources, and has some security mechanisms.
This is auto reboot poe power supply when the PD equipment are frozen.
The working mechanism of the SNMP protocol is very simple, mainly through a variety of different types of messages, that is, PDU (protocol data unit) to achieve the exchange of network information.
However, managed switches are much more expensive than unmanaged switches described below. [1]
Used to track traffic and sessions
industrial design: -40℃~+80℃ working temperature and redundant power input, IP40 level, according with the requirements of the EMC industrial level 4, DIN-Rail mounting or wall mounting, support redundant ring network (Recovery time<20ms), RSTP, STP and MSTP protocol, satisfied the reliable and practical requirement of industrial control for network system, the reliable hardware design is specially used for industrial communication continuous running.
